- Introduced `__get_nexus_s3_client` method to create an S3 client for the nexus bucket. - Updated `upload_traces` and `get_trace_file` methods to use the new nexus S3 client and bucket settings. - Added nexus bucket and region names to the BedrockFileDatabase class for improved configuration management.
- Updated `upload_traces` and `get_trace_file` methods to utilize the nexus S3 client and bucket. - Adjusted exception handling to reflect changes in the S3 client usage.

Hello @AlisoSouza, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!
Summary of Changes
This pull request introduces changes to the bedrock.py file within the nexus/task_managers/file_database directory. The primary goal is to enable the uploading and retrieval of trace files from a separate S3 bucket (referred to as the 'nexus' bucket) in addition to the existing Bedrock bucket. This involves adding new configuration settings, initializing a new S3 client specifically for the nexus bucket, and updating the upload_traces and get_trace_file methods to use the new client and bucket.
Highlights
- New S3 Client: A new S3 client (
nexus_s3_client) is initialized to interact with the nexus S3 bucket, separate from the Bedrock S3 bucket. - Configuration Settings: New configuration settings (
AWS_S3_BUCKET_NAMEandAWS_S3_REGION_NAME) are introduced to specify the nexus S3 bucket and region. - Trace File Handling: The
upload_tracesandget_trace_filemethods are updated to use thenexus_s3_clientandnexus_bucket_namefor uploading and retrieving trace files.
Changelog

Code Review
The pull request introduces functionality to upload and retrieve trace files to/from an S3 bucket, specifically for Bedrock agents. It involves adding new S3 client configurations and methods for uploading and retrieving data. The changes seem reasonable, but there are a few areas that could be improved for clarity and maintainability.
Summary of Findings
- Duplicated S3 Client Logic: The code introduces a new S3 client (
nexus_s3_client) that mirrors the existing one (s3_client). Consider refactoring to avoid duplication and improve maintainability. - Missing Error Handling: The
upload_tracesfunction lacks explicit error handling. Adding error logging or raising exceptions would improve the robustness of the code. - Inconsistent Naming: The naming convention for the new S3 client and related variables could be more consistent with existing conventions.
Merge Readiness
The pull request introduces important functionality, but there are some areas that need improvement before merging. Specifically, the duplicated S3 client logic and missing error handling should be addressed. I am unable to approve this pull request, and recommend that it not be merged until the high severity issues are addressed. Please have others review and approve this code before merging.

This function duplicates the logic in __get_s3_client. Consider refactoring to avoid duplication. You could potentially pass the region name as an argument to a single __get_s3_client function.

return boto3.client(
"s3",
region_name=region_name

Consider adding error handling to this function. If upload_fileobj fails, it would be helpful to log the error or raise an exception.
try:
bytes_stream = BytesIO(data.encode('utf-8'))
self.nexus_s3_client.upload_fileobj(bytes_stream, self.nexus_bucket_name, key)
except Exception as e:
print(f"Error uploading trace file: {e}")

Consider adding a comment explaining why you need a separate nexus_bucket_name and nexus_region_name. Is it pointing to a different bucket or region than the original bedrock configurations?

It seems like you are creating a new s3 client for nexus. Is there a specific reason for creating a new client instead of using the existing self.s3_client? If it's for separation of concerns, consider documenting this decision.

The return value [] in the except block might be misleading. It suggests an empty list of traces, but it actually indicates that the trace file was not found. Consider returning None or raising an exception to better reflect the situation.
except self.nexus_s3_client.exceptions.NoSuchKey:
return None # Or raise an exception
